Abstract

An actuator for driving a test element is proposed. The test element comprises a lancet for perforating a skin portion of a living organism. The actuator comprises an engaging part for engaging and driving the test element to perform a lancing motion. The actuator further comprises a lancing actuator and a lancing spring, wherein the lancing actuator is adapted for biasing the lancing spring by executing a forward movement and thereby exerting a biasing force on the engaging part. The actuator further comprises a latch element, wherein the latch element is a force-sensitive latch element, wherein the latch element is adapted for exerting a retention force holding back the engaging part, The retention force counteracts the biasing force. The latch element is adapted for releasing the engaging part when the biasing force exerted by the lancing actuator exceeds the retention force exerted by the latch element, thereby allowing for the test element to perform the lancing motion.
